apumonlmeaoctober 13 192s. serial No. 142,008.

i This invention relates to linings-'for shoes and more particularly to an auxiliary'lining` for the heel portion of a shoe,fespec1.ally a low shoe, to prevent the same from slipping up and down and chafing the foot.

Numerous attempts have heretofore been made to provide Qa satisfactory anti-slip lining of the general character in questlon, which will cling to the stocking and wlnch will also firmly adhere to the shoe and remain in theQ proper position. Linings have been madeof cloth, of leather and of rubber.

' Although rubber is an excellent material on account of its non-slip properties, ithas been found in practice that it is practically impos- A sible to secure the rubber lining to the shoe in such a way that it will remain in position and noti work loose. Experiments have shown that ordinar adhesives will not effectively hold a rub er lining to the'1shoe.

The object of the present invention is to provide an improved method of mak1ng an auxiliary lining of the type referred to, which lining shall poess exceptional non -slip and cushioning properties, and which will, at the same time, remain securely attached to the shoe counter for indefinite periods.

In order that the invention may be read-k ily understood, reference is had to the accomtplanying drawing, forming part of this spec1` cation, and in which 'Figure 1 is an enlarged fragmentary sectional view of the material from which my im roved linings are manufactured;

igure 2 is asimilar view illustrating my first step intreating this materlal;

Figure 3 is a plan view showing how the blanks 'are cut from a sheety of material such as illustrated in Figure 2; f

Figure 4 is a fragmentary sectional view on an enlarged scale, showing another step 1n the manufacture of myimproved limngs;

Figure 5 is a face view of one of my'completed linings; n p,

Figure 6 is a transverse section on an enlarged scale on the line 6-6 of Figure 5; and

Figure 7 is a perspective view showing thel shape of my improved lining when in use.

Referring to the drawings in detail, the material from which I manufacture my improved linings consists of a sheet of. soft rubber l, preferably sponge rubber, to each face of which is permanently united or secured a piece of fal ric 2, such, for example, as

` rubber.

The sheet consisting of the sponge or otherI soft rubber and fabric, as shown in Figure l, is now coated on both sides with an 'adhesive such as glue or thelike, as indicated at 3 1n Figure 2., After the adhesive coated sheet has dried sufficiently, I then cut from it blanks of the desired shape, as indicated` at in Figure 3. These blanks are preferably of the shape shown, having a rounded upper edge and provided in the middle of the lower edge with a V-shaped notch b, in order to enable the lining to better conform with the. curve of the shoe heel. fl

After the blanks A have been cut out fro the sheet, they are split centrally, as by means of a knife or the like X, in the manner shown in Figure 4, so that each blank forms a lair` of linings. Each such lining, therefore, comprises a facing l or lb of sponge rubber,"- and abacking 2 of fabric coated with ad'- hesive 3.

The finished lining is shown in Figures 5 and 6. In these figures is shown a lining'u a having a sponge rubber facing 1IL and a fabric backing 2 provdied with a coating 3 of adhesive..` v Preferably the upper curved edge of the.v

lining is thinned or beveled, as shown at c, .90

the adhesive and the lining is then placedin I position in the shoe.

I find Lthat the glue or adhesive forms alf.V

10 ric 2 and the shoe, and thus, the fabric being` i secure and permanent bond. between the fabfirmly united to the rubber, by vulcanizing or otherwise, the rubber is effectively lield in position and prevented from working'.-

loose. In other words, the difficulties hereto ,105- foreencountered in connection with, rubber linings are overcome by interposing a piece of fabric between the rubber and the shoe,` the fabric being firmly united-with therubber.. I find that the adhesive will effectively 110 stick to the fabric and hold the same in the shoe, while experience has shown that it will not stick to or properly hold rubber alone.

What I claim is 1. The method of making auxiliary heel linings which comprises forming a sheet of sponge rubber between two pieces of fabric to which the rubber is vulcanized, cutting from such sheet blanks of the desired shape, and then splitting each blank to form a lining having a face of sponge rubber and a fabric backing.

2. Tile method of making auxiliary heel linings which comprises forming a sheet of sponge rubber between two pieces of fabric to which the rubber is vulcanized, coating the fabric on both sides of the sheet with adhesive dryin'g the same, cutting from such sheet blanks of the desired shape, and then splitting each blank to form a lining havin Y a sponge rubber face and a backing of a lesive coated fabric.

3. The method of making auxiliary heel linings which comprises securing a piece of fabric to each side of a sheet of s onge rubber, coating tbe outside of the fa ric on both sides of the sheet with adhesive, drying tbe same, cutting from such sheet blanks of the desired shape, and then splitting cach blank to form a lining having a sponge rubber face and a backing of adhesive coated fabric.-

In testimony whereof I aflix my signature.
